ASTRALite developed the first ever 2-in-1 scanning topo-bathy LIDAR on a UAV that can seamlessly survey and map with a single survey. This system provides previously unavailable and highly desired 3D data from a platform capable of reaching inaccessible and hard to map areas. In addition, the output can be viewed in real-time giving the customer immediate visibility of cracking, misalignment, settlement, erosion and undermining of slabs and foundation elements to a revolutionary 1 cm accuracy or better.
